I am not able to reproduce this crash on amd64 & on ubuntu.com.
I get another one though (occurs frequently & always w/ gmail on the
desktop) and as far as I can tell systematically w/ the following stack
trace:
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
Core was generated by `webbrowser-app --app-id=GMailmailgooglecom
--webapp=R01haWw= --maximized --enab'.
Program terminated with signal 11, Segmentation fault.
